The cost of replacement of the door shutters selected as samples, their transportation to the laboratory and cost of testing by the laboratory shall be borne by the contractor, and shall be deemed to be included in the lump sum rates quoted in Schedule ‘A’ Part I.

2. Adhesives 2.1 Nature of the surface to be bonded when bonding to walls, the regularity of the age of plaster or cement screeds should be particularly noted. The area to be bonded together with the size of panels, tiles, etc, should be stated. 2.2 Location of the installation Not only should mention be made of internal and external locations. But the actual conditions of service, i.e. maximum temperature, Humidity, structural movement, etc should also be assessed.

2.3 Assembly technique Possible conditions of site assembly should be noted and

Page 3 restrictions on technique assessed, i.e. whether it is possible to apply adhesive to both surfaces, whether it is necessary to position the assembly after making the bond etc. Furnished with these facts, most adhesive suppliers will suggest suitable products from their range for the purpose in mind and give assembly details and costing. 2.4 Application: the required preparation of the surfaces to be bonded should also be carried out carefully. All surfaces should be firm and free from dust. Loosed material on brickwork, etc, should be removed by thorough use of a wire brush. Surfaces with a high gloss should be roughened with or emery. It is usually necessary to make sure that the surfaces are dry, and to protect the job from rain if necessary during assembly. 2.5 Clean tools should always be used for applying the adhesive. When making an overall bond (e.g. with contact adhesive) care should be taken to obtain an even film of adhesive. On porous surfaces it may be necessary to apply two coats to ensure an adequate dry film on the surface. 2.6 A large number of adhesion failures are caused by using an incorrect drying time. When a two-way dry-stick is used it is essential that the manufacturers’ instructions are closely followed on this point. If the drying time is too long, then the two adhesive films will not fuse completely and once again a poor bond will result. A similar effect will be obtained once again a poor bond will result. A similar effect will be obtained if the adhesive films are not thoroughly pressed into contact. With most adhesives high pressure to the assembly to bring the two bonding surfaces into intimate contact must be removed before applying adhesive.

Page 19 may be (a) a high pressure (small air aperture) type or (b) a low pressure (large air gap) type, depending on the nature and location of work to be carried out. Skilled and experienced workmen shall be employed for this class of work. Paints used shall be brought to the requisite consistency by adding a suitable thinner. Spraying should be done only when dry condition prevails.

5.5 Each coat shall be allowed to dry out thoroughly and rubbed smooth before the next coat is applied. This should be facilitated by thorough ventilation.

5.6 Each coat except the last coat, shall be lightly rubbed down with sand paper or fine pumice stone and cleaned of dust before the next coat is laid.

5.7 Each coat except the last coat shall be lightly rubbed down with sand paper or fine pumice stone and cleaned of dust before the next coat is laid.

5.8 No left over paint shall be put back into the stock tins. When not in use, containers shall be kept properly closed.

11.1.2 Primer for Wood work / Iron & Steel / Plastered / Aluminium surfaces shall be as specified below:

Page 21 SN SURFACES PRIMER TO BE USED a Wood work (hard & soft wood): Pink conforming to I.S.3536- 1966 b Resinous wood and ply wood: Aluminium primer c Iron & Steel, Aluminium and galvanised Steel work: Zinc chromate primer conforming to I.S. 104-1962. d Plastered surfaces, cement brick work, Asbestos surfaces Cement Primer for oil bound distemper and paint:

11.1.3 The primer shall be ready mixed primer of approved brand and manufacture.

11.2 Preparation of surface :

11.2.1 Wood work: The wood work to be painted shall be dry and free from moisture.

11.2.1.1The surface shall be thoroughly cleaned. All unevenness shall be rubbed down smooth with sand paper and shall be well dusted. Knots, if any, shall be covered with preparation of red lead made by grinding red lead in water and mixing with strong glue sized and used hot. Appropriate filler material with same shade as paint shall be used where so desired by the Architects.

11.2.1.2 The surface treated for knotting shall be dry before painting is applied. After the priming coat is applied, the holes and indentation on the surface shall be stopped with glaziers putty or wood putty (for specifications for glaziers putty and wood putty- refer as mentioned here-in-before). Stopping shall not be done before the priming coat is applied as the wood will absorb the oil in the stopping and the latter is therefore liable to crack.

20.0 BEES WAXING OR POLISHING WITH READY MADE WAX POLISH :(NEW WORK):

Page 22 20.1 Materials: The polishing shall be done with bees waxing prepared locally or with ready made wax polish of approved brand and manufacture, as stipulated in the description of item.

b) Where bees waxing is to be prepared locally, the following specifications for the same shall apply:

Pure bees wax free from paraffin or stearing adulterants shall be used. Its specific gravity shall be 0.965 to 0.969 and melting point shall be 63o C. The polish shall be prepared from a mixture of bees wax, linseed oil, turpentine and in the ratio of 2: 1.5: 1: 0.5 by weight.

The bees wax and boiled linseed oil shall be heated over a slow fire. When the wax is completely dissolved, the mixture shall be cooled till it is just warm and turpentine and varnish added to it in the required proportions and the entire mixture shall be well stirred.

20.2 Preparation of surface: Preparation of surface will be as mentioned here-in-under para 32.20.2 with the exception that knotting, holes and cracks shall be stopped with a mixture of fine dust formed of the wood being treated, beaten up with sufficient bees wax to enhance cohesion. 20.3 Application: The polish shall be applied evenly with a clean soft pad of cotton cloth in such a way that the surface is completely and fully covered. The surface is then rubbed continuously for half an hour.

When the surface is quite dry, a second coat shall be applied in the same manner and rubbed continuously for one hour or until the surface is dry.

The final coat shall then be applied and rubbed for two hours (more if necessary) until the surface has assumed a uniform gloss and is dry showing no sign of stickiness.

The final polish depends largely on the amount of rubbing which should be continuous and with uniform pressure, with frequent changes in the direction

1 Other details: The specifications for painting (General) as mentioned here-in- before shall hold good as for as they are applicable.

2 FRENCH SPIRIT POLISHING: (ON NEW WORK WITH A COAT OF WOOD FILLER):

21.1 Polish: Pure varying from pale orange to lemon yellow colour, free from resin or dirt shall be dissolved in methylated spirit at the rate of 140 gm. of shellac to 1 litre of spirit. Suitable pigment shall be added to get the required shade. 21.2 Preparation of surface: The surface shall be cleaned. All unevenness shall be rubbed

Page 23 down smooth with sand paper and well dusted off. Knots if visible shall be covered with a preparation of red lead and glue size laid on while hot. Holes and indentations on the surface shall be stopped with glaziers putty. The surface shall then be given a coat of wood filler made by mixing whiting(ground chalk) in methylated spirit at the rate of 1.5 kg. of whiting per litre of spirit. The surface shall again be rubbed down perfectly smooth with glass paper and wiped clean.

21.3 Application: The number of coats of polish to be applied shall be as described in the Iem. A pad of woolen cloth covered by fine cloth shall be used to apply the polish. The pad shall be moistened with the polish and rubbed hard on the wood, in a series of overlapping circles applying the mixture sparingly but uniformly over the entire area to give an even level surface. A trace of linseed oil on the face of the pad facilitates this operation. The surface shall be allowed to dry and the remaining coats applied in the same way. To finish off, the pad shall be covered with a fresh piece of clean fine cotton cloth, slightly damped with methylated spirit and rubbed lightly and quickly with circular motions. The finished surface shall have a uniform texture and high gloss.
